三系杂交早籼稻新组合红优2155于2011—2012年连续2 a在福建上杭县试种示范,表现生育期适中、植株较高大、群体结构较好、穗大粒重、丰产性较好,但感稻瘟病、抗倒伏性较弱,可在上杭县稻瘟病轻发地区作双季早稻种植。介绍了该组合在上杭县的高产栽培技术。 Hongyou 2155, a new three-line early indica hybrid rice variety, was tested in Shanghang, Fujian Province for 2 consecutive years from 2011 to 2012. The results showed that the three-line early hybrid rice combination had a moderate growth period, higher plant height, better population structure, But the sense of blast, lodging resistance is weak, can be in Shanghang County rice blast light area for double season early rice planting.
